Abstract: The single skin frame drum has a clamp rim for tightening or slackening its membrane (1) which is fixed on the resonance body (6) of the instrument. The membrane is pre-formed hat-shaped on the resonance body and secured at the edge in a rim (12). The inner diameter of the rim is slightly greater than the outer diameter of the resonance body.

Abstract: The invention relates to a method for preparing an albumin isolate from a substance containing albumin, according to which the substance is first ground to a flour and the flour suspended in an aqueous solution. The albumin is then extracted from the flour and introduced into the solution by means of at least one countercurrent protease. The albumin is extracted from the solution by precipitation using a mineral acid and then neutralized. The aim of the invention is to improve said method in such a way that the albumin is extracted from the solution and introduced into the solution by way of a process comprising at least two steps and carried out using the at least one protease, at a pH greater than 8 and at a temperature of between 30 and 60  DEG C. In the first step the flour is treated at a lower concentration of the at least one protease, in relation to albumin weight, at a lower pH and at a higher temperature than in the second step. After the first step a first upper flow of a fraction containing the flour is separated and the albumin separated from said fraction by precipitation, and after the second step a second upper flow of a fraction containing the flour is separated and fed back to the first step.

Abstract: A tagging device comprises a strap attached to a housing. A latch plate is mounted on a first length of strap and a collar is slidably mounted on a second length of strap. The latch plate has two location pegs which fit into holes on the first length of strap such that a hole fits over the lug to make the strap the correct size for a user. Two flexible barbs are formed on the collar such that the collar slides over the plate and the barbs are deformed as they slide up slopes on the plate. As the barbs slide off the end of the slopes they return to their rest position and snap into slots. Moving the collar in relation to the plate once the barbs have snapped into place in the slots causes the barbs to break, giving an indication of tampering.

Abstract: A method and system for fusing a region in the spine involve the use of at least one guide tube (10a) to pass instruments and substances into the spinal region in a minimally invasive manner. In the preferred practice of the method, a guide tube is anchored to a vertebra and the guide tube is moved to thereby position the vertebra. A steerable drilling tool (20a) is passed through the guide tube and steered into position to abrade at least a portion of an intervertebral disc, thereby creating a cavity in the disc.  A flowing substance is passed into the cavity and permitted to solidify to establish fusion in the cavity. Optionally, an uninflated balloon (40) is inserted into the cavity and the balloon is filled with the flowing substance to contain the flowing substance.

Abstract: This invention is a multiple access communication technique by which a multitude of transmitters communicate with receivers using direct sequence spread spectrum signaling. The direct sequence codes are reused by a large number of simultaneous transmitters, so the system is named Code Reuse Multiple Access ("CRMA"). This reuse method requires only a small number of codes relative to the number of simultaneous transmitters, and can use as few as one code for all the users. The direct sequence codes are not required to have special properties such as maximal length. The lengths of the spreading codes employed are not necessarily related to the bit or symbol interval. CRMA can be implemented on a Paired Carrier Multiple Access ("PCMA") system with or without a novel receiver structure which is also described.
